mindspore.ops.NPUClearFloatStatus

class mindspore.ops.NPUClearFloatStatus(*args, **kwargs)[source]

Clears the flag which stores the overflow status.

Note

The flag is in the register on the Ascend device. It will be reset and can not be reused again after the NPUClearFloatStatus is called.

Examples: see NPUGetFloatStatus.

Inputs:

input_x (Tensor) - The output tensor of NPUAllocFloatStatus. The data type must be float16 or float32.

Outputs:

Tensor, has the same shape as input_x. All the elements in the tensor will be zero.

Supported Platforms:

Ascend

Examples

>>> alloc_status = ops.NPUAllocFloatStatus()
>>> get_status = ops.NPUGetFloatStatus()
>>> clear_status = ops.NPUClearFloatStatus()
>>> init = alloc_status()
>>> flag = get_status(init)
>>> clear_status(init)
